Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for receiving Cell Broadcast Short Message Service (CBS) messages in a CDMA communication system, comprising: receiving a CDMA message having encapsulated therein a broadcast SMS message; processing a designated field or subfield of the CDMA message to determine whether the broadcast SMS message is a GSM CBS message or a CDMA broadcast SMS message; and recovering the GSM CBS message from the CDMA message if the GSM CBS message is encapsulated in the CDMA message.
2. The method of claim 1 , wherein the designated field is an address length field of the CDMA message, and wherein the GSM CBS message and CDMA broadcast SMS message are distinguished by different values for the address length field.
3. The method of claim 2 , wherein a header portion of the GSM CBS message is carried in an address field of the CDMA message.
4. The method of claim 1 , wherein the designated subfield is a broadcast type subfield in an address field of the CDMA message, and wherein the GSM CBS message and CDMA broadcast SMS message are distinguished by different values for the broadcast type subfield.
5. The method of claim 1 , wherein the designated field is a burst type field of the CDMA message, and wherein the GSM CBS message and CDMA broadcast SMS message are distinguished by different values for the burst type field.
6. The method of claim 1 , wherein the designated field is a language field for an address field of the CDMA message, and wherein the GSM CBS message and CDMA broadcast SMS message are distinguished by different ranges of value for the language field.
7. The method of claim 6 , wherein a partial header portion of the GSM CBS message is carried in the address field of the CDMA message.
8. The method of claim 6 , wherein a serial number, a message identifier, and a page parameter of the GSM CBS message are carried in the address field of the CDMA message.
9. The method of claim 1 , wherein the CDMA message is a Data Burst Message in the CDMA system.
10. The method of claim 9 , wherein the GSM CBS message is encapsulated in an SMS Deliver Message that is further encapsulated in an SMS Broadcast Message that is then encapsulated in the Data Burst Message.
11. The method of claim 10 , wherein a message encoding field of the SMS Deliver Message includes a value indicative of the GSM CBS message being carried in the SMS Deliver Message.
12. The method of claim 10 , wherein a service category parameter of the SMS Broadcast Message includes a value indicative of the GSM CBS message being carried in the SMS Broadcast Message.
13. The method of claim 1 , wherein the CDMA system is a cdma2000 system.
14. A method for processing Cell Broadcast Short Message Service (CBS) messages for transmission in a CDMA communication system, comprising: forming a Data Burst Message to carry a GSM CBS message; setting a designated field or subfield of the Data Burst Message to a value indicative of the GSM CBS message being carried in the Data Burst Message; and broadcasting the Data Burst Message carrying the GSM CBS message to terminals.
15. The method of claim 14 , wherein the GSM CBS message is encapsulated in an SMS Deliver Message that is further encapsulated in an SMS Broadcast Message that is then encapsulated in the Data Burst Message.
16. A method for processing Cell Broadcast Short Message Service (CBS) messages for transmission in a CDMA communication system, comprising: encapsulating a GSM CBS message in a CDMA SMS Deliver Message; setting a message encoding field of the SMS Deliver Message to a value indicative of the GSM CBS message being carried in the SMS Deliver Message; encapsulating the SMS Deliver Message in a CDMA SMS Broadcast Message; and setting a service category parameter of the SMS Broadcast Message to a value indicative of the GSM CBS message being carried in the SMS Broadcast Message.
17. The method of claim 16 , wherein the SMS Broadcast Message is encapsulated in a Data Burst Message, and wherein a designated field or subfield of the Data Burst Message is set to a value indicative of the GSM CBS message being carried in the Data Burst Message.
18. A terminaoperative to receive Cell Broadcast Short Message Service (CBS) messages in a CDMA communication system, comprising: a demodulator/decoder operative to process data samples and provide a CDMA message having encapsulated therein a broadcast SMS message; and a message processor operative to process a designated field or subfield of the CDMA message to determine whether the broadcast SMS message is a GSM CBS message or a CDMA broadcast SMS message, and to recover the GSM CBS message from the CDMA message if the GSM CBS message is encapsulated in the CDMA message.
19. An apparatus operative to receive Cell Broadcast Short Message Service (CBS) messages from a CDMA communication system, comprising: means for receiving a CDMA message having encapsulated therein a broadcast SMS message; means for processing a designated field or subfield of the CDMA message to determine whether the broadcast SMS message is a GSM CBS message or a CDMA broadcast SMS message; and means for recovering the GSM CBS message from the CDMA message if the GSM CBS message is encapsulated in the CDMA message.
20. A network entity operative to process Cell Broadcast Short Message Service (CBS) messages for transmission in a CDMA communication system, comprising: a buffer receive data for a GSM CBS message; and a message processor encapsulate the GSM CBS message in a CDMA SMS Deliver Message and to further encapsulate the SMS Deliver Message in a CDMA SMS Broadcast Message, wherein a message encoding field of the SMS Deliver Message and a service category parameter of the SMS Broadcast Message are set to values indicative of the OSM CBS message being carried in the SMS Deliver Message and the SMS Broadcast Message.
